description
441 Stainless Steel Alloy Description:
Type 441 is a nominal 18% chromium-bearing ferritic stainless steel stabilized with columbium. The alloy provides good high-temperature strength that exceeds that of type 409 and 439 stainless steels. Type 441 offers good corrosion resistance in many exhaust gas environments, equivalent to that of 439 and 18 Cr-Cb stainless steels.
